Does anyone know where the water heater bypass valves or water pump are are located in a 17RK? My best guess is under the plywood floor of the bed/mattress but I thought I should ask you before I take that apart.

As justman said it should be close to the hot water tank. Looking at exterior pictures of the 17RK it looks like the tank is located on the front-left corner which would put it under the queen bed. I see there is under-bed storage access from the front-right corner - can you see the back of the tank when looking in the storage access door?

Thanks ttavasc. I don't believe I can see the back of the tank from the under bed storage but will have another look in the daylight tomorrow. I emailed Joyco and the Dealer where I purchased the trailer as well

In my JF X213 I had to unscrew 2 plywood panels under my dinette seats to access the water heater bypass under the right one and the pump and the winterizing diversion valve under the left one. You may have to do some disassembly to access yours too.

Lift the panel under the bed and you have access to the furnace, water heater and pump. I saw the bypass valves there. They also have tubing and valves installed to be able to draw in anti-freeze in the same access location.
